What is the correct restart when a player curses at a teammate after a misplay, before the referee blows the whistle?

When a player curses at a teammate after a misplay, the action is typically considered unsporting behavior. Before the referee blows the whistle, the play continues, and the referee does not stop the game for this type of verbal misconduct.

In this scenario, since there was no infringement of the Laws of the Game that would warrant a stoppage, the correct restart is a throw-in. The team that did not touch the ball last before it went out of play is awarded that throw-in.

It is also important to understand that the choice of a free kick or a penalty kick would only be applicable in situations involving a foul or an offense against an opponent, which does not apply here. A goal kick is specific to instances when the attacking team last touches the ball before it goes out of play over the goal line without resulting in a goal. Thus, the situation described fits the context of a throw-in as the most appropriate restart.
